Yes they do damage hair. Every time I have tried one ,I wound up looking like a Q-tip or my head looked like cotton. A perm will damage even more and look worse if you have been coloring your hair. There's chance of it looking okay if you don't color your hair.
It depends on how much curl you want. Most stylists use an acid perm for grey hair because it is more resistant to chemicals. Alkaline perms are often used for colored hair and natural hair. If youâre okay with a more soft curl, then I would go for the alkaline perm because it will be easier on your hair.
